Gold has shed more than 10 percent since touching a peak of $1,365.23 an ounce in mid-April, weighed down by a stronger dollar and rising US interest rates.
Spot gold was flat at $1,227.26 per ounce by 2:50 p.m. EDT (1850 GMT), after touching its weakest since July 14, 2017 at $1,220.81.
US gold futures for August delivery settled up 60 cents, or 0.1 percent, at $1,227.90 per ounce.
"In this environment where we also see oil prices falling, and so less concern from investors about rising inflation, that's another negative for the gold price," said Jens Pedersen, senior analyst at Danske Bank in Copenhagen.
Gold is regarded as a hedge against inflation.
The US dollar slightly eased off a three-week high. It earlier rose across the board, after Powell gave an upbeat outlook for the US economy.
Higher interest rates tend to boost the dollar and push up bond yields, making greenback-denominated gold more expensive for holders of other currencies and denting its appeal.
Russia, which dropped off the list of US Treasuries holders in May, may have increased gold purchases as a result of recent sanctions imposed by the United States on Russia, analysts said, but that has yet to help bullion prices.
"Not so much of that is going to turn the market around," said Jeffrey Christian, managing partner of CPM Group.
Longer-term, some analysts expect dollar strength to wane and possible geopolitical concerns and the heavy weight of gold bearish positions to help bullion recover.
Meanwhile, silver dipped 0.1 percent at $15.56 an ounce, after touching $15.38, its lowest since July 10 of last year.
Platinum lost 0.2 percent at $814.20 an ounce, after earlier hitting a two-week low of $798.14.
Palladium dipped 0.5 percent at $906.47 per ounce after hitting $902.97, the weakest since April 9.
